Gauges 10-14-24-30-39-48, 10-14-09-12-18-28. Rare Phosphor Bronze Acoustic Strings are a departure from the standard, good-quality bronze string currently available--not necessarily better, but possessing a new, different, and stronger voice. Hand-carved archtops, dreadnoughts, and good steel string acoustic guitars of rosewood, maple, and mahogany benefit from a distinct improvement in tone, depth, and sustain with a fatter, louder sound and a deeper bottom.

I was amazed to discover the unopened set of strings packaged in "non-corrosion" packaging badly corroded. The DR box pontificated proudly on their special packaging which evidently did not do the job. I buy strings ahead in bulk so I can restring as needed. What a shock to open a fresh package of DR strings to find them unacceptably corroded. To Musician's Friend's credit, they comped me a new set, but complained that I had had them over 45 days which put them past their warranty period. My question was, "How can I know if strings are corroded if I do not open them until I need them." The salesman said he buys strings ahead as well, so kind of understood the problem. Perhaps MF's policy on unopened strings should extend 2 years or some more reasonable period.

I had used Martin Marquis for my 12-string to date but always felt that there was more crispness that should be coming from the guitar. I am very happy with the full bass and strong overtones and resonance (between strings). Also, this set doesn't sound thin at all tuned down a whole step (which I always do to extend the life of my 12-string).

Had been using elixir 10-47 nanos on my new Taylor 854ce with spruce/rosewood, and it sounded so thin I considered selling it. Tried these DR P/B uncoated 10-48's and it's a whole new guitar. I can't stop playing it. I even have to turn it down when playing amplified, compared to the settings I used for elixirs, and they're half the price. I'm sure elixers are fine on some guitars, but my Taylor loves DR's!
